Part 2-42: Tests – Static side load for strain relief

1

Scope

This part of IEC 61300 specifies a test to determine the influence of a side load applied to a
cord assembled with a strain relief. The intention is to simulate a static load, due to a length of
fibre cable, which would typically be experienced during service. Components should withstand
side loads during optical transmission without degradation of the optical performance. Besides
a boot, any feature that controls the bending radius of the fibre can be considered as strain
relief.

General description

The specimen is inserted into the test apparatus as shown in Figure 1. A load, equivalent to
several metres of cable, is applied to the cable attached to the device under test and any
changes in optical attenuation are recorded during the specified period of the test.
NOTE This test is applicable only to those passive optical components where the product design incorporates fibre
cable pigtails.

4
4.1

Apparatus
Load generator

The load generator consists of a mass and a means of clamping the mass to the cable. The
clamping shall not introduce micro- or macro-bending losses in the cable.


–6–
4.2

BS EN 61300-2-42:2014
61300-2-42 © IEC:2014

Holding fixture

The holding fixture consists of a means to hold the device under test in a stable and

representative manner. For connectors, the holding fixture shall incorporate an adaptor where
required. The holding fixture shall be capable of accommodating those devices where the input
and output fibre cables are co-located on the same side of the device.
4.3

Optical source and detector

The optical source and detector used to measure changes in attenuation shall comply with that
specified in IEC 61300-3-4.
A device to record attenuation over time (X, t) should be used where the optical detector does
not have the capability to monitor continuously (i.e. where the sample rate is <10/min).

5
5.1

Procedure
Preparation of specimens

Prepare the specimens according to the manufacturer’s instructions or as specified in the
relevant specification. The device under test shall be terminated with a sufficient length of fibre
cable to facilitate interfacing with the optical source and detector.
5.2

Pre-conditioning

Pre-condition the device under test for 2 h at the standard test conditions as given in
IEC 61300-1, unless otherwise specified in the relevant specification.
5.3

Initial measurements

Complete initial examinations and measurements on the specimen as required by the relevant
specification. Measure and record the attenuation of the device under test.
5.4

Conditioning

The body of the specimen shall be mounted in a representative manner onto the holding fixture
(see Figure 1). The clamp to which the load can be applied shall be fastened to the cable in
such a manner that the optical fibre or cable is not crushed. Unless otherwise specified, the
point of load application shall be 20 cm to 30 cm from the end of the strain relief.

5.5

Measure the attenuation

Re-measure the attenuation to ensure that the fixturing and cable clamping have not affected
the cable's attenuation.
5.6

Apply cable load

Gradually apply the specified load to the cable clamping fixture, being careful to avoid any
sudden jerking or straining of the cable. Maintain the load for recommended duration (or as
specified in the relevant specification).
5.7

Monitor attenuation

The attenuation of the specimen shall be continuously monitored during the test, as described
in IEC 61300-3-3, unless otherwise specified in the relevant specification. Any deviation in the
device attenuation from that measured in 5.5 shall be considered attributable to the
cable/device interface, or fibre-to-fibre interfaces in the device.
If there are unacceptable changes in attenuation and it is questionable whether the cable itself
may be at fault, a control test to determine cable contribution should be performed in the same

manner using a piece of cable and two cable clamps.
5.8

Recovery

Allow the specimen to remain under standard test conditions for 2 h at the standard test
conditions as given in IEC 61300-1, unless otherwise specified in the relevant specification.

BS EN 61300-2-42:2014

Final measurements and examinations

On completion of the specified duration, remove all fixtures and make a final attenuation
measurement to ensure that there is no permanent damage to the device under test. The
results of the final measurement shall be within the limit established in the relevant
specification.
Remove the device from the mounting fixture and, unless otherwise specified, visually examine
the specimen in accordance with IEC 61300-3-1. Check for evidence of any degradation in the
specimen. This may include, for example:
–

broken, loose or damaged parts or accessories;

–

breaking or damage to the cable jacket, seals, strain relief, or fibres;

–

displaced, bent, or broken parts.

5.10

Repeated testing

Where required by the relevant specification, the test shall be repeated with the load applied in
mutually perpendicular directions as permitted by the product design. For example, a product
with a base plate extending beyond the fibre exit may prohibit loading in that direction. The
number of mutually perpendicular directions employed shall be defined.

6

Severity

The severity of the test is dependent upon the tensile load applied and the duration, as
recommended in Table 1.
